After updating : no connection

Hi,

i have upgraded form 1.1 to 1.5 and it does not connect anymore to my ISP's FTP ( Hetnet)

It is not stabile, their FTP, but it used to work fine ...
I have searched and downloaded an older version,
and it works again, so it is not the FTP, but the software.

Please support your claim with logs, screenshots, version informations etc.

Thanks
-Mat
